# How Many Amps Does a Projector Use?

Projectors have become common home and office appliances due to their compact design and high functionality with better resolution. You might wonder how many amps a projector use. Well, there will be a detailed answer to the questions.

Depending on the projector type and model, it may use 1.9 amps while running on 117V AC. This is the figure when you turn the projector on. But after a few minutes, the amperage will drop to 1.65 amps.

There are some other factors related to the power consumption of a projector. Let’s introduce you to them and show you how to calculate the power consumption of a projector.

**Projector Power Consumption Calculator**

To know how much power your projectors consume, you must know the wattage of the projector. Projectors can draw from 50 watts to 350 watts depending on the size and model. The power input also depends on the brightness of the projector bulb.

Here will be a step-by-step process to calculate the power consumption of your projector. Make sure you follow along.

**Determine the Wattage**

The first thing you need to know is the wattage of the projector. You might find the data on the label of the projector power supply. If you don’t see it there, check the manufacturer’s website to know the wattage. Let’s say you have found 500W on the label. It means the projector will use 500W of electric energy per hour.

**Determine How Long the Projector Runs**

To calculate the power consumption, you need to determine the watt-hours. You can get it by multiplying the wattage of the device by the hours it runs every day. Say your projector runs for 2 hours a day. So, the power consumption will be 500 watts x 2 hours = 1,000 watt-hours per day.

**Convert the Power Consumption**

The standard unit for power consumption is Kilowatt-hours or kWh. You can divide the above figure by 1,000 to convert it to kWh. So, your projector should consume 1,000 Wh / 1000 = 1 kWh per day.

**Calculate the Electricity Cost**

You need to know the rate your utility company charges per unit to calculate this. You can check the electricity bill for the previous month to find out the rate. Now, multiply it by the daily power consumption calculated above.

Let the rate is $0.50 per unit. So, the daily cost of running your projector will be 1kWh x $0.50 = $0.50. If you accumulate the price for one month, it will sum up to $0.50 x 30 = $15.

So, this is how you calculate the power consumption of your projector.

**How Many Watts Does a Projector Use?**

As we have already mentioned, this depends on the size and model of the projector you buy. Projectors come in different technologies. A **laser projector** won’t use the same watts as an LED or LCD projector.

On average, a projector will draw somewhere between 50-350 watts, depending on its technology.

**How Much Power Does a Mini Projector Use?**

All the tiny projectors you might see out there will run on a battery. This is because mini projectors are mostly designed for portability and inexpensiveness.

They are usually powered by Li-ion batteries and consume about 50-90 watts per hour, depending on the brand and model. Some specific models can even draw less than that, but we exclude them as they aren’t usable for regular tasks.

**How Much Power Does a DLP Projector Use?**

DLP projectors consume the maximum power of all projector types. Though these projectors have an age-old technology, they are very popular due to their affordability.

Depending on the projection mode, the service life of the projector, light source, etc., a DLP projector will draw between 150 and 350 watts.

**How Much Power Does an LCD Projector Use?**

Well, LCD projectors are a bit different from the previous type. They will consume about 150 watts per hour, varying depending on the model and usage. In this type of **projector screen**, you can dim the brightness more than in DLP projectors, so these projectors draw less power than them.

**How Much Power Does a LED Projector Use?**

LED projectors use a lot less power than other projectors. As the light source is LED here, these projectors will consume one-third power of regular projectors.

Depending on the projector mode, brightness, and other factors, you can expect your Epson LED Projector to use approximately 30-150 watts. Some other models might consume even less depending on the technology used.

**Final Words**

As there are many factors to consider when you want to calculate the power consumption of a projector, the process isn’t easy. You might use **rear projection** in a certain mode, and the consumption should change.

We went through the complex calculation and made it simpler for you to easily understand and calculate how many amps a projector use. This short yet informative guide should help you to calculate the power your projector uses in a certain period.
